tá

adverb. then, then, [ᴹQ.] at that time [past]

A word for “then” appearing in a list of demonstratives from 1968, a vowel-lengthened form of ta “that” (VT49/11). It reappeared in some notes from 1969 alongside a variant tai (VT49/33). ᴹQ. tá “then, at that time (past now)” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948, where Tolkien indicated it was specifically used to refer to the past (PE23/109), as opposed to ᴹQ. en “then” referring to the future.
